Hi Matthew,
but from what I know, not all HTTP responses have "Content-Length" field.
responses with "chunked" payload are one of them. what can I do then?
Thank you.

Sockets (SSL or otherwise) are layer-3 objects while content is a layer-7

>>my problem with above code is, if I set select timeout to a small
time, I can't guarantee that all data is received (because some servers
are really slow), and if I set timeout to a long time (5-10 seconds), my socket
is getting stucked in wait-state for a long time and I can't use the response
before that.
I tried to make this work by using "BIO_should_read()" or
"BIO_pending()" functions, but none of them is giving me what I want.
so, Is there a way to determine when exactly there is nothing else to
read on the SSL socket?
